内容摘要:

Based on the work of O'Grady and Voisin, Markman proved the Hodge conjecture for abelian fourfolds of Weil type with discriminant 1 using hyper-Kähler manifolds of generalized Kummer type. I will present a short new proof of this theorem which is very recently discovered in my joint work with Salvatore Floccari. Our strategy is to use O'Grady's 6-dimensional singular symplectic varieties, and as an advantage, our proof does not rely on the theory of hyper-holomorphic bundles.
